LOCK.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed July 12, 1918. Serial No. 244,546.

To all whom it may concern Be it known that I, JOHN T. STEEN, a citizen of. Finland, residing at Waukegan, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to improvements in keyless locks of the pad-lock type, and while it is more particularly intended to be employed on sea-bags such as are used by sailors or marines, in which the mouths of such bags are provided with spaced apart eyelets through which the prongs of a staple are extended in such a Way that the mouth of the bag can be contracted by sliding said eyelets in the proper direction on said prongs and secured or locked in said contracted or closed position by a lock engaging said prongs, yet it is applicable for use for various other purposes, in fact wherever a pad-lock may be used, and it con sists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to produce a lock of the above named general character that shall be simple and inexpensive in construction, strong, durable, eficientin operation and so made that it cannot be unlocked without a knowledge of the combinations of the lock.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In the accompanyin drawings which serve to illustrate an em odiment of the invention Figure 1 is a face view of the lock.

Fig. 2 is a sectional view taken on l ne 2--2 of Fig. 1 looking in the directlon 1ndicated by the arrg ws.

Fig. 3 is a face view with the operat1ng knob and dial plate on which sald knob is mounted, removed, showing the members of the lock in their locked positions.

Fig. 4 is a group view showing the members comprising the lock in detached perspective relation to one another.

Fig. 5 is a similar view of like parts to that shown in Fig. 3, but illustratlng the lock in its unlocked position.

Fig. 6 is an enlarged sectional view taken on line 6-6 of Fig. 5 looking in the direction of the arrows, and

Fig. 7 is an enlarged sectional view taken on line 7-7 of Fig. 5 looking in the direction of the arrows.

Like numerals of reference refer to corresponding parts throughout the difl'erent v1ews of the drawings.

The casing of the lock is indicated in the difi'erent views of the drawings by the reference numeral 10 and as clearly shown in Fig. 4 of the drawings, has in its walls a number of slightly elongated openings 11 which are arranged in pairs and are for the reception of the prongs 12 and 13 of the staple which is designated as a whole by the reference numeral 14. One of the prongs,

for example the prong 13, is provided on its inner surface with a series of ratchet teeth 15 to engage a locking dog as will be presently explained. The casing 10 is preferably annular in shape and has one of its ends closed and its other end provided with a shoulder 16 on which the dial plate 17 may rest and be secured in any suitable manner. Snugly fitted in the casing to rest'on the bottom or closed end thereof is a disk 18 which has at its periphery a sleeve or loop 19 which is located between the openings 11 of one pair of said openings so as to register therewith in such a manner that one of the prongs of the staple 14 can be extended therethrough as well as through the above mentioned openings 11 in the casing. The disk 18 can be secured to the bottom or closed end of the casing 10 in any suitable manner and has extended centrally therefrom a spindle 20 which is by preference riveted to the disk 18 and is of sufficient length to extend through a suitable opening 21 in the dial plate. The disk 18 is provided diametrically opposite each other with a pair of projections 22 spaced from the spindle 20 and extended in the same direction. These projections are preferably formed by being punched from the disk 18 as is clearly shown in different views of the drawings. Near one of the projections or standards 22 the disk 18 is provided with a post 23 on which is mounted one end of a pawl or locking-dog 24: which has at its free end lateral extensions 25 and 26 to engage the ratchet teeth 15 of the staple and the tumblers of the lock respectively. The disk 18 is provided on its inllllt ing the spindle 20 thereon is the base or lower tumbler 29 which is provided in its periphery with a slot 30 and on its upper surface with a pin 31 which is located about midway between the opening 32 in said tumbler and its periphery. Mounted on top of the tumbler 29 is a spacin member 33 which is in the form of a bro en ring and has at diametrically opposite points a pair of marginal recesses 34 which are for the purpose of engaging the standards 22 on the disk 18. This spacing member is provided with a cut away portion 35 to permit it to be placed in position without interference with the sleeve 19 on said disk. Located on the upPer surface of the spacing member 33 is an intermediate tumbler 36 which is of the same construction as the tumbler 29 except that the tumbler 36 has a pin 37 projecting from each of its faces as is clearly shown in Figs. 2 and 4 of the drawings. Mounted on the upper or outer surface of the tumbler 36 is another spacing member 38 which is of the same con struction as the s acing member 33 and above described; 11 the upper or outer surface of the last named spacing member is mounted the uppermost or outer tumbler 39 which has in its periphery a recess 40 to receive the lateral extension 26 on the pawl 24 when the parts of the lock are placed in the positions. they will assume when the staple is unlocked as is clearly shown in Fig. 5 of the drawings. The tumbler 39 is I provided on its upper or outer surface with a cylindrical projection 41 which has an opening 42 to receive the outer portion of the spindle 20 on which the tumbler and its projection 41 is closely fitted. As shown in Figs. 2 and 6 of the drawings the projection 41 extends through the central opening 21 of the plate 17 which has a graduated scale 42 surrounding said opening. Firmly fitted on the outer portion of the projection 41 of the tumbler 39 is a cap 43 which has on its inner portion an annular flange 44 provided with an indicator 45 to be used in pointing out the numbers or graduated marks on the scale 42 of the dial late. This cap 43 is surrounded by a mille operating knob 46 which is firmly secured in place on the cap 43 so as to turn therewith as well as with other members of the lock. The tumbler 39 has on its inner surface a pin 47 which is adapted to engage the pin 37 on the tumbler 36, that is, that portion of saidpin which is located between the tumbler 36 and the tumbler 39, the other portion of the pin 37 beinrr adapted for engagement with the pin 31 on the base or lower tumbler 29 all of which tumblers are mounted for rotation on the spindle 20 but closely fitted thereon.

In the operation of setting the combinations of the lock, the staple is withdrawn from the openings therefor in the casing, when by looking through the opening 11 at 5 on the dial, and by turning the knob to the right the recess 30 on the base tumbler can be seen when it is located in position to receive the extension 26 on the pawl; when by taking a reading of the dial the indicator will show the first number of the,

combination.

Now, by turning the knob to the left, the recess 30, on the intermediate tumbler 36 can be seen when in position to receive the extension 26 on the pawl, when by reading the dial the second number of the combinationwill be shown. After this, the knob is turned to the right until the spring 28 actuating the pawl causes its extension to fit into the recess 40 of the tumbler 39 when by reading the dial the third number of the combination will be shown.

By my improvements, I provide a lock with practically unlimited combinations, that is, the combination of each lock can be made a different one from any other, by changing the location of the pins on the tumblers with respect to the recesses in said tumblers, or by changing the location of the indicator with respect to the recess on the outer tumbler.

Having thus fully described my invention what I claim as new, and desire to secure by Letters Patent, is

1. In a lock of the class described, the combination with a casing having a pair of openings on each side of a line extended diametrically through the casing, of a staple having teeth on the inner surface of one of its prongs and adapted for insertion into and withdrawal from said pairs of openings, a centrally located spindle and a pair of projections extended within the casing, a base, an intermediate and an outer tumbler rotatably mounted on said spindle and each having a peripheral recess. a spacing member interposed between the base tumbler and the intermediate tumbler and having marginal recesses to engage the aforesaid projections, a spacing member interposed between the intermediate tumbler and the outer tumbler and having marginal recesses to engage said projections, said base and outer tumblers having on their adjacent faces a pin. said intermediate tumbler having a coinciding pin or projection on each of its faces to engage the first named pins, means on the outer tumbler to turn the same, a spring actuated pawl pivoted in the casing mamas for movement toward and from said spindle and having at its free portion oppositely disposed extensions adapted to alternately engage the tumblers and the toothed prong of the staple.

2. In a lock of the class described, the combination with a casing having a pair of openings on each side of a line extended diametrically through the casing, of a staple having teeth on the inner surface of one of its prongs and adapted for insertion into and withdrawal from said pairs of openings, a disk fitted in the casin and secured to one end thereof and having integral therewith a sleeve located between the openings of one pair thereof and in register therewith, said disk having a centrally located spindle extended therefrom within the'casing and a pair of integral projections spaced from said spindle and extended into the casing, a spring actuated pawl mounted on the disk for movement toward and from said spindle and having at its free portion oppositely disposed extensions, a base, an intermediate and an outer tumbler rotatably mounted on plate, a turning knob secured on sai said spindle and each having a peripheral recess, a spacing member interposed between the base and intermediate tumblers and having marginal recesses to engage the projections carried by the said disk and a cut away portion in its periphery, a spacing member interposed between the intermediate and outer tumblers and having marginal recesses to engage said projections and a cut away portion in its periphery, said base and outer tumblers having on their adjacent faces a pin, said intermediate tumbler having a coinciding pin or projection on each of its faces for engagement with the first named pins, a cap fitted on the outer portion of the outer tumbler and having an indicator for registering with graduations upon a dial p and a dial plate surrounding the outer tumbler and closing the end of the casing adja cent to said tumbler.
